Community Management

Feature Description

A community is a large group of people brought together by common topics, and multiple topics can be created under the same community based on different interests. A community is used to manage members. All its topics are shared among members, who can send and receive messages independently.




Community Group Management

Topic group

The community-group-topic hierarchy is implemented as follows: The groupCustomField field in the community profile defines a field to store the topic group list of the community. The customData field in the topic profile stores the group to which each topic belongs.
When a community is loaded, the groupCustomField field for the topic group list in the community (group) profile is used to display the group list.
When the topic list of a community is loaded, the customData field in the topic profile is used to get the group name for assignment.
Note
1. You can customize the key value of the groupCustomField field for the topic group list of the community (group). The following sample code names it topic_category.

Configuring the group list for the community

You only need to modify the groupCustomField field in the group profile. The key value is the name of the field for the topic group list you defined.
Sample
// Topic group list
const categoryList = ['Group 1', 'Group 2'];
// Update the topic group list of the community
let promise = chat.updateGroupProfile({
  groupID: 'group1',
  // You need to configure the custom group field `topic_category` in the console first.
  groupCustomField: [{ key: 'topic_category', value: JSON.stringify(categoryList) }]
});
promise.then(function(imResponse) {
  console.log(imResponse.data.group) // Detailed group profile after modification
}).catch(function(imError){
  console.warn('updateGroupProfile error:', imError); // Error information
});

Getting the list of groups in the community

Sample
let promise = chat.getGroupProfile({
  groupID: 'group1',
  groupCustomFieldFilter: ['topic_category']
});
promise.then(function(imResponse) {
  console.log(imResponse.data.group);
  const categoryList = []; // Topic group list
  const { groupCustomField } = imResponse.data.group;
  groupCustomField.forEach((item) => {
    if (item.key === 'topic_category') {
      // Parse the group list
      categoryList = JSON.parse(item.value);
    }
  });
}).catch(function(imError){
  console.warn('getGroupProfile error:', imError); // Error information
});

Adding a topic to a group

You can save the topic group with the customData field of the topic.
Sample
// Define a group for the topic
const customData = { category: 'Group 1' };
// Update the topic group
let promise = chat.updateTopicProfile({
  groupID: 'group1', // Community ID
  topicID: 'topic1', // Topic ID
  customData: JSON.stringify(customData),
});
promise.then(function(imResponse) { // Topic group updated successfully
  console.log(imResponse.data.topic); // Modified topic profile
}).catch(function(imError) { // Failed to update the topic group
  console.warn('updateTopicProfile error:', imError);
});

Getting the topic group

Use the customData to parse the JSON content after getting the topic list.

Listening for topic callbacks

Sample
let onTopicCreated = function(event) {
   const groupID = event.data.groupID // ID of the community to which the topic belongs
   const topicID = event.data.topicID // Topic ID
   console.log(event.data);
};
chat.on(TencentCloudChat.EVENT.TOPIC_CREATED, onTopicCreated);
let onTopicDeleted = function(event) {
   const groupID = event.data.groupID // ID of the community to which the topic belongs
   const topicIDList = event.data.topicIDList // List of deleted topic IDs
   console.log(event.data);
};
chat.on(TencentCloudChat.EVENT.TOPIC_DELETED, onTopicDeleted);
let onTopicUpdated = function(event) {
   const groupID = event.data.groupID // ID of the community to which the topic belongs
   const topic = event.data.topic // Topic profile
   console.log(event.data);
};
chat.on(TencentCloudChat.EVENT.TOPIC_UPDATED, onTopicUpdated);
